Searching Google for the following I only found uninformed crap. What is this?

looris@Palace-of-the-Nine-Moons:/tmp $ tree /TheVolumeSettingsFolder/
└── HFSExtentTables
        └── UBNUIHU3QNGCTMAO8ECAQ65960

2 directories, 2 files

The two files are binary data (file just says "data" and strings returns nothing useful).

If they are, as the name would imply, actually "volume settings", how can I know which volume they refer to?

I couldn't find any definitive documentation, either. The term "HFS extent tables" refers to the data organization scheme of the HFS filesystem, but I don't understand why those would exist as file data instead of metadata. What's the format of your root drive? Do you share the volume over the network? –  jmk Feb 2 '13 at 21:12
@jmk format is HFS+ journaled, and only the public folders of each user are shared. –  o0'. Feb 3 '13 at 11:01
